And then Bobby walked in...

Prompt: Bobby walks in
Summary: You know Dean, I TOLD you to lock the door…
Rating: M (for the beginning part)
Warnings: Bobby's mouth, Dean having his way with Sammy All that good stuff.

Sam moaned, back arching as Dean's tongue trailed down his neck towards his chest, disregarding his shirt entirely by wrenching it off. If it ripped, neither brother really cared all that much, concentrating more on just FEELING one another.
It had been a long, annoying, boring hunt and Dean was getting fed up with Cas sending them off around the US to take care of God's problems. Right now, he was going to ignore whatever responsibility he had and fuck his little brother into the mattress because hey, this was their sin, and they were more than happy to keep on sinning.
The elder Winchester sat up only long enough to pull off his coat and over shirt, Sam sitting up to help him out of his undershirt, before they fell back on the bed again, mouths connected. Sam moaned again, tongue battling with his brother's, tugging impatiently at the belt loops of his pants. Dean laughed into their kiss and Sam growled, biting his bottom lip and sucking harshly before letting go and attacking his neck.
Sam knew Dean liked it when he was assertive, even though he ALWAYS ended up on the bottom (which was perfectly fine by him, he liked bottoming out to Dean).
Dean's hands fiddled with the belt around Sam's waist, pulling it off and throwing it to a random corner of the room. He groaned as Sam bit at his neck, laving his tongue along the bite marks when he was done before bending his head to nip at his collarbone.
"Fuck, Sam…"
Sam didn't listen, pushing up so his brother was sitting on his knees, leaning forward so he had access to his chest. He kissed down and along the golden skin, mewling prettily as he tasted his sibling's skin. Dean groaned again, fighting hard to not let Sam continue, he really wanted to let him go on, but he knew he couldn't. Grabbing the back of Sam's head by his hair, he tugged him away from his chest.
Another mewl, much more whine-like this time.
"Deeeean…"
Dean just about lost his self control when Sam keened his name like that. Instead, he leaned down and proceeded to attempt to suck his soul out through his mouth. He pulled back after a few moments, a line of saliva still connecting their eager mouths.
"Ah Sammy, if you keep that up we're never gonna get to the best part baby."
Sam whined in annoyance, once more tugging at his brother's belt loops.
"Then hurry up!"
He was unceremoniously pushed back onto the bed, Dean ravaging his neck with bites and kisses.
"Impatient little slut aren't you?"
Sam groaned, arching up into Dean's mouth.
"Only your slut big brother."
"Damn fucking straight you are."
Dean undid the button and fly of Sam's jeans, gripping the denim and pulling it harshly down his brother's legs. In seconds, it was gone, across the room and in god knew which corner, to be forgotten until a later date.
Dean was about to grab his brother's boxers when…
"JESUS FUCKING CHRIST-"
Dean nearly toppled off the bed in shock.
Instead, he whipped around to see what Sam was staring at, blushing ten different shades of red. (Damnit, Sam was only supposed to blush like that when Dean was whispering dirty things to him!)
There, in the doorway, stood none other than Bobby Singer, eyes wide and mouth open.
"….Uhm…This isn't it looks like?" Sam offered meekly.
"The hell it isn't!"
"…We aren't the hunters you're looking for?"
"Dean, Jedi mind tricks aren't REAL."
"Damnit."
Sam kicked Dean's knee, basically meaning "get off!", but he didn't move. The three males were watching one another cautiously, or, Bobby was watching Sam and Dean, Sam was watching Dean in case he decided he didn't care Bobby was there and continued ravishing him, and Dean was glaring at Bobby.
"You know…" Sam said quietly. "I DID say lock the door…"
Dean had the decency to look sheepish.
All was silent for a good five minutes before Bobby spoke again.
"Dear god. I knew your daddy fucked you up but I didn't know he fucked you up THIS bad."
"Hey!" Dean said indignantly. "I jumped Sam of my own volition thanks!"
"On Halloween when I was sixteen…"
"Yes, yes, details details. You looked hot."
"I was covered in dirt and blood."
"Hence hot."
"You worry me."
"I should."
"Boys, still standing here."
They fell silent again.
Sam was feeling decidedly awkward just about now, laying there in his boxers, older brother straddling his hips. It was sort of a compromising position to be in when it was just the two of them, but with Bobby there it was a lot worse. Clearing his throat, he tried to shift out from under Dean to no avail. His brother just wasn't budging.
"Did you need something Bobby?" Dean finally asked. "Or can I get back to making Sam scream?"
"DEAN!"
The ten different shades of red had multiplied to a good forty.
"Well, I was gonna say we should go get a drink and a few girls, I can tell you're busy. I'll be down at the bar if you boys need me."
He turned around and was about to leave, before turning again and saying;
"Oh yeah, and, if you two are gonna be screwing around, lock the door. And you're paying for the soundproofing on the room at my place. Later!"
And he was out the hotel room door again, closing it behind him and walking off.
Sam gaped at the closed door, while Dean just looked sort of smug.
"…..I really wonder about Bobby sometimes."
"Hey, the man is gonna let us soundproof our room, that means you don't have an excuse when we're at Bobsters."
Sam's eyes widened.
"Dean Alan Winchester don't you fucking da-"
Sam's words were entirely lost as his brother jumped him again.
